Thank you for choosing Profoto.

Follow the instructions in this booklet to use your new product.

Thanks for showing us your confidence by investing in a ProRing. For more than three decades we have sought the perfect light. What pushes us is the conviction that we can offer even the most demanding photographer yet better tools.

Before our products are shipped we have them pass an extensive and strict testing program. We check that they pass the quality and capacity levels the most demanding photographers require. For this reason our flash equipment is the standard in most rental studios in New York and Tokyo and the most rented flash all over the world.

Quality of Light

The Profoto system consists of different generators built and designed to meet the demands of the most demanding photographers. Yet the most important thing is the light you create and it is then essential that the system offers freedom to create your own light. The light source, both the flash tube and the modeling light, is placed high and free in the flash head. This makes it easier for you to adjust the light and use your creativity. Most reflectors can be moved forward or backward in relation to the optical centre of the light source, effectively narrowing or widening the spread of the light and changing the intensity and fall-off characteristics as well.

Every single reflector and accessory creates its special light and the unique Profoto focusing system offers you a possibility to create your own light with only a few different reflectors.

Enjoy your Profoto product!

ProRing

The ProRing is an entirely mobile source of light. The interior diameter of 100 mm provides plenty of space for professional camera lenses. Since the camera holder can be tilted forward and backwards, as well as upwards and downwards, most cameras can be attached. This makes an excellent source of light in cramped areas, for example the interior of an automobile. Many fashion photographers also use the ProRing to find new angles and capture details. The ProRing provides a very distinct, directed light, but can be complemented by a soft or a widesoft Reflector, which increases the light source, thereby producing a softer light with fewer sharp shadows. For close ups, there is a reflector that focuses the light 50 cm in front of the camera lens. The ProRing modeling light is controlled by a ON/OFF switch at the back. The modeling light consists of ten 12

V 20 W halogen lamps. The ProRing is equipped with a Ozone free High Power Quarts flash tube for unlimited use.
